    Groundwater animals

    Get PDF
    Groundwater animals are adapted to live in environments with no light and limited nutrients, They can provide insights into fundamental questions of evolution, ecology and biodiversity. They also have an important role to play in informing the reconstruction of past changes in geomorphology and climate, and can be used for characterising aquifers. The BGS is undertaking a systematic survey of selected areas and lithologies in the UK where groundwater animals have not been investigated. This is important because little is known about groundwater ecosystems in the UK despite the unique contribution to biodiversity made by these animals. Groundwater organisms are also thought to provide ecosystem services by means of their role in nutrient cycling and natural remediation of pollutants in the subsurface. They may also be useful indicators of human impacts on groundwaters

    Methods of isolation and identification of pathogenic and potential pathogenic bacteria from skins and tannery effluents

    Currently there is no standard protocol available within the leather industry to isolate and identify pathogenic bacteria from hides, skins or tannery effluent. This study was therefore carried out to identify simple but effective methods for isolation and identification of bacterial pathogens from the effluent and skins during leather processing. Identification methods based on both phenotypic and genotypic characteristics were investigated. Bacillus cereus and Pseudomonas aeruginosa were used as indicator bacteria to evaluate the isolation and identification methods. Decontaminated calfskins were inoculated with a pure culture of the above mentioned bacterial species followed by a pre-tanning and chromium tanning processes. Effluent samples were collected and skins were swabbed at the end of each processing stage. Bacterial identification was carried out based on the phenotypic characteristics; such as colony appearance on selective solid media, cell morphology following a standard Gram-staining and spore staining techniques, and biochemical reactions, e.g., the ability of a bacterial species to ferment particular sugars and ability to produce certain enzymes. Additionally, an identification system based on bacterial phenotypic characteristics, known as Biolog® system was applied. A pulsed-filed gel electrophoresis (PFGE) method for bacterial DNA fingerprinting was also evaluated and used for the identification of the inoculated bacteria. The methods described in the study were found to be effective for the identification of pathogenic bacteria from skins and effluent

    Inflation in Supersymmetric Cosmic String Theories

    We examine a non-Abelian SUSY SU(2)×U(1)SU(2) \times U(1) gauge theory and a SUSY U(1) theory originally used to investigate the microphysics of cosmic strings in supersymmetric theories. We show that both theories automatically include hybrid inflation. In the latter theory we use a DD term to break the symmetry. SUSY is broken during inflation and restored afterwards. Cosmic strings are formed at the end of inflation. The temperature anisotropy is calculated and found to vary as (MGUT/MP)2(M_{GUT}/M_P)^2.Comment: 5 page

    Patient Evaluation of Emotional Comfort Experienced (PEECE): Developing and testing a measurement instrument

    Get PDF
    Objectives: The Patient Evaluation of Emotional Comfort Experienced (PEECE) is a 12-item questionnaire which measures the mental well-being state of emotional comfort in patients. The instrument was developed using previous qualitative work and published literature. Design: Instrument development. Setting: Acute Care Public Hospital, Western Australia. Participants: Sample of 374 patients. Interventions: A multidisciplinary expert panel assessed the face and content validity of the instrument and following a pilot study, the psychometric properties of the instrument were explored. Main outcome measures: Exploratory and confirmatory factor analysis assessed the underlying dimensions of the PEECE instrument; Cronbach’s α was used to determine the reliability; κ was used for test–retest reliability of the ordinal items. Results: 2 factors were identified in the instrument and named ‘positive emotions’ and ‘perceived meaning’. A greater proportion of male patients were found to report positive emotions compared with female patients. The instrument was found to be feasible, reliable and valid for use with inpatients and outpatients. Conclusions: PEECE was found to be a feasible instrument for use with inpatient and outpatients, being easily understood and completed

    Superconducting Cosmc Strings and Primordial Magnetic Fields

    Full text link
    We consider grand unified theories with superconducting cosmic strings and which admit the mechanism for generating primordial magnetic fields recently discussed by Vachaspati. We show that these models are severely constrained by cosmological arguments. Quite generically, either stable springs or vortons will form. Provided the mass per unit length of the strings is sufficiently large, these stable configurations will overclose the Universe.Comment: BROWN-HET-830, 14 pages, use phyzz

    Divergence of NHS choice policy in the UK: what difference has patient choice policy in England made?

    No full text
    OBJECTIVES: To examine the types of choices available to patients in the English NHS when being referred for acute hospital care in the light of the divergence of patient choice policy in the four countries of the UK. METHODS: Case studies of eight local health economies in England, Scotland, Northern Ireland and Wales (two in each country); 125 semi-structured interviews with staff in acute services providers, purchasers and general practitioners (GPs). RESULTS: GPs and providers in England both had a clear understanding of the choice of provider policy and the right of patients to choose a provider. Other referral choices potentially available to patients in all four countries were date and time of appointment, site and specialist. In practice, the availability of these choices differed between and within countries and was shaped by factors beyond choice policy, such as the number of providers in an area. There were similarities between the four countries in the way choices were offered to patients, namely lack of clarity about the options available, limited discussion of choices between referrers and patients, and tension between offering choice and managing waiting lists. CONCLUSIONS: There are challenges in implementing pro-choice policy in health care systems where it has not traditionally existed. Differences between England and the other countries of the UK were limited in the way choice was offered to patients. A cultural shift is needed to ensure that patients are fully informed by GPs of the choices available to them
